Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a ridge trimming machine, in which mud soil is dug up to build up on old ridges, and the piled up soil is compacted. The present invention relates to a trimming machine for spraying a drug such as an anti-proliferative agent.

2. Description of the Related Art Conventionally, paddy fields are used to make ridges, to store water by damming them, to serve as a boundary with other people's rice fields, or as a sidewalk for agricultural work.

Conventionally, various machines for making ridges, that is, those using a lever-crank mechanism as a rectifying machine, those using hydraulic pressure, and the like are known. These ridge trimming machines are used to scrape a part of the old ridges and raise the soil obtained by dug up the soil of the paddy field to the remaining old ridges, and tap or sway this embankment to compact it. is there.

Problems to be Solved by the Invention However, since the conventional ridge trimming machine simply remakes the ridges, it is unavoidable that grass grows on the ridges, and when the ridge grasses grow, the ventilation of the rice in the rice field becomes airy. It had to be mowed later because it would worsen and hinder the sun.

Means for Solving the Problems In order to solve the above-mentioned problems, the present invention was built up by a soil raising means for shaving old ridges in a machine frame, excavating mud soil in a paddy field and raising the ridges, and the soil raising means. In a trimming machine having a trimming board for trimming mud, a deformable arm is projectingly provided on the machine frame, a pipe body is supported at a tip thereof, and a branch pipe is provided on the pipe body. Provided with a nozzle facing the ridge side surface and the ridge upper surface, which are arranged on the ridge, and supplying and spraying a medicine from a medicine supply device provided on a tractor for pulling the machine frame to these nozzles. To do.

The deformable arm can adjust the position of the nozzle provided at the tip of the deformable arm, and since the nozzle is provided so as to face the side surface and the upper surface of the ridge, the medicine can be sprayed on each surface. When this drug is sprayed on the surface of a new ridge, it can be sprayed evenly on the whole surface with a small amount without leakage, which is efficient. At this time, if the old ridges are scraped off and grasses and the like are removed and then embankment is performed, the adhesion can be improved. Then, by spraying, for example, a rush-generation inhibitor on the ridged surface, it is possible to prevent ridge-generation.

Embodiment Next, an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

Although the ridge striking device 5 is not shown, a cylinder is provided in the sleeve 5a, a piston is provided in the cylinder, and the piston rod is fixed to the sleeve, so that oil can be supplied and discharged by the plunger pump. The sleeve can be reciprocated by the accompanying movement of the piston. The cylinder has a quadrangular shape that fits the inner surface of the sleeve, and a rotation stopper plate that slides on the inner surface is attached to the inner surface to prevent the sleeve and the piston rod from rotating. Further, double coil springs are provided between the whirl-stop plate and the inner surface of the sleeve upper plate to fulfill the function of promoting return. Details are described in Japanese Examined Patent Publication No. 63-12562, and these can also be used.

A ridge striking plate 6 conforming to the upper and side shapes of the ridge is rotatably attached to the piston rod, is rotatably and returnably provided on the ridge, and the surface having a fluff is provided. The front fur 6a (Amelin Buffalo fur) is attached.

The cylinder is rotatably supported by a support frame 7, and a rotation range of a sleeve and the like is limited by a vertically extending rod 7a and rubber 7b which are rotatably provided together with the cylinder. The support frame 7 is attached to the vertical movement device 8. This vertical movement device

The vertical movement device itself is fixed to the mounting plate 8f, and the mounting position of the mounting plate with respect to the main machine frame 1 can be changed by moving the oblong hole to a bolt or the like from the main machine frame. .

Reference numeral 9 denotes a tail wheel having a support shaft 9a and wheels 9b, and the support shaft is attached to a fitting cylinder 9c attached to a projecting arm of the main machine frame 1 so as to be positionally adjustable.

A deformable arm 10a is attached to the fitting cylinder 9c,
The drug sprayer 10 is attached to this. Drug sprayer 10
Has a nozzle 10c and a branch pipe 10d in the pipe body 10b, and a nozzle 10e in the branch pipe. Nozzle 10c is the side of the ridge
10e faces the upper surface of the ridge. The drug is supplied to the tube body 10b from the drug supply device shown in FIG. 2 and sprayed in a mist form from the nozzles 10c and 10e.

In FIG. 2, on the front side of the tractor T, a frame body 12 is connected to an underframe 11 of the tractor, and a medicine supply device 13 is provided on this frame body. In the medicine supply device, the medicine from the medicine tank 13a is pressurized by the spraying pump 13b and supplied to the pipe body 10b of the medicine dispersion body 10 through the conduit 13c, and the medicine is atomized from the nozzles 10c and 10e. It is supposed to be sprayed on.

Next, a method of using the trimming device of the present invention will be described.

The ridge arranging machine A is connected to the tractor in a predetermined posture and arranged at a predetermined position on the old ridge, and the position of the tail wheel 9 and the position of the ridge striking plate 6 are adjusted. Next, when the tractor is run to move the ridge trimmer A, the rotor 2 operates in the reverse direction to scrape a part of the ridge and excavate the soil of the paddy field to raise it to the old ridge. The ridge striking plate 6 strikes and compacts this. On the new ridge formed in this way, the spray pump 13b is operated and the drug spray 1
The drug is sprayed from each of the nozzles 10c and 10e of 0.
As a result, the drug is sprayed on the surface of the new ridge, and therefore, if the agent for preventing the occurrence of rush is used as the drug, the overgrowth can be prevented.

The above was sprayed on the new ridge, but as shown in Fig. 1, the same nozzle as above was placed on the inner surface of the cover 3a, and the soil was excavated by the rotor 2 and the scraped soil of the old ridge was treated with chemicals. May be sprayed. In this way, the drug is sprayed to the inside of the new ridge, so that the effect is increased.

The drug is not limited to a liquid, and may be in the form of powder, and may be a herbicide, a soil conditioner, a coating agent, etc., in addition to the agent for preventing the occurrence of rush.

In addition, as the structure for operating the ridge striking plate, any of a hydraulic pressure having a switching valve, a lever-crank mechanism, a cam mechanism and the like can be used, and the rotor may be provided in parallel with the ridge.

According to the present invention, the machine frame is provided with a deformable arm, the pipe main body is supported by the arm, the pipe main body is provided with branch pipes, and the pipe main body and the branch pipes are provided with nozzles. Since it is made to face the side and top of the ridge, specifically, the nozzle is deformed with respect to the side and top of the ridge according to the condition of the ridge in different situations such as high and low, so that it is in an optimal state. Since the nozzles can be positioned and the nozzles are provided on the side surface and the upper surface of the ridge, respectively, the medicine can be reliably sprayed on the side surface and the upper surface of the ridge. If, for example, an agent for preventing the occurrence of ridges is used as a drug in such a state, it is possible to perform ridge-plant prevention treatment at the same time as adjusting the ridges, and it is possible to eliminate the removal work because ridges do not grow on new ridges. . When the chemicals are sprayed on the new ridges, they can be evenly sprayed on the surface of the embankment without leakage, so that the non-sprayed part can be efficiently eliminated. The new ridges are prepared by shaving the old ridges and removing grasses, etc., and the ridges are then laid up and laid up so that the soil can adhere well and strong ridges can be made.
